How to deal with slight wear on the pump shaft when the eddy current magnetic pump is idling?

Let's first understand the structural principle of the eddy current magnetic pump, which is made of FRPP material/PVDF material. The pump is driven by magnetic force. The shaftless seal design is simple and easy to install. It can be used together with a filter for filtering. It is an important choice for environmental protection, electroplating, chemical and other mechanical equipment.

So the high probability of idle speed may be due to insufficient flow, for the following reasons: Insufficient flow of eddy current magnetic pump is mostly caused by air leakage in the suction pipe and bottom valve; Water inlet blockage; Not enough attempts were made to enter the bottom valve; The speed of the eddy current magnetic pump is too low; Excessive wear of sealing ring or impeller; Excessive water absorption, etc.

The handling method includes: checking the suction pipe and bottom valve, blocking the leakage gas source; Clean up sediment or blockages at the inlet; The water depth of the bottom valve must be greater than 1.5 times the diameter of the inlet pipe, and the water depth of the bottom valve should be increased; Check the power supply voltage, increase the speed of the magnetic pump, and replace the sealing ring or impeller; Reduce the installation position of the eddy current magnetic pump or replace the high head pump.
